Fixes to sprite phase 2 so that sprite X reads use the exact same slot as on hardware in the case that there are fewer than the max number of sprites on each line. Re-read sprite Y from SAT cache during phase 2 and properly mask the calculated row. Fixes remaining issues with spinning cube scene in Overdrive 2.
